TO ALL WIIOM IT MAY CONCERN:

I ie it known that I, MILTODIV. NOBLES, of Elmira, in the county ofGheinung, and State of New York, have invented certain new and useful'Improvements in Boat-Connccting and Detaching Apparatus; and I dohereby declare the followingvto he afull, clear, and exact descriptionof the same, reference being had to the accompanying drawings, making apart of this specitication, in' whieh- Figure 1 representsa top plan ofahoat, with the connecting and detaching apparatus in place, `the hailsbeing represented as dropped down on the decks.

Figure 2 represents a vertical cross-section through the boat,representing onegoi` the hails as raised up, and ready to receive thedavit-block hook. l y

Similar letters of reference, where they occur in the separate figures,denote like parts of the apparatus in both.`

My invention relates more especially to such holding-heads as arejointed seras to drop down and lieupon the boat'when not in us, and thushe out of the'way. And my invention consists in raising up, locking, andunlocking the holding device, by the operation -of a single level', orof a. single shaft, thus simplifying and rendering more eflicient andexpeditious the connecting and detaching apparatuskand putting the wholeoperatin in the hands of a single persen, so that no confusion oruntimed action can be had by a multiplicity of orders, or division ofthe manipulations.

'To enable others skilled in the art to make and use my invention?, Iwill proceed to describe the same with reference to the drawings. y

A represents. the holding-heads, one at or near each endet' the boat.These heads pass through `the kcelson B, and through the decks C,andjust abolve the decks arejointedl, as at @the npperportions A',having the connecting and disconnecting apparatus combined with them, aswill he explained, and also the bail or brace, by which the boat ispreventedfrom tipping or rocking, as it isliable to do when hung by its'centre. Upon the upperportions ofthe heads A are arranged, first, ahinged arm, b, having a hole, c, in or through it, into which the pointof the hook d takes and holds. The hooks cZ are hinged to the tops ofthe holding-heads, as at e, and are held over towards the hinged armwith whichit acts by a spring, f, which constantly tends to force it inthat direction, though it yields when the hook is forcibly moved in anoppositedirection. A bail or brace, g, united at its crown to the head,and hinged at the sides of the boat, as at Zz, which hinges are in linewith that in the head a, prevents the boat from rocking or tipping whensuspended to the davit-blocks, and admits of its dropping with the headwhen the lat-ter is detached, a. rubber or other spr-ing,1.', tending tothrow down said head and bail. Longitudinally of the boat, and lowenough down not to be in the way, thereis arrangeda rocking-shafnzl),furnished with a lever, j, by which it may he operated. i On each end ofthe shaft D there is a wrist or crank, 7c, to which is connected a rod,Z, that passes through the deck, and on top of which the head A', whendown, rests or lies, and to which crank or wrist is also connected arod, m, extending up through the deck, and jointed as at a1., in linewith the other joints a la Z1., so as to yield with them; and theextreme upper end of the rod m is linked, as at o, to the jointed arm b,Athese devices being duplicated at the ends, or at each of theholding-heads. y

A modification of `the herein-described plan may be made by placing thetackle-hook below, and allowing the balancing-rod or arm to pass througha guide on or near the tackle-block.

The operation is as follows: supposing the holding-heads to be lyingdown, as shown in iig. 1, the shaft D is turned,l and its cranks c raiseup the rods Z against the heads A', and thus raise up the heads into avertical or nearly so position. At the same movement of the cranks c therods m are moved up, and they in turn raise the hinged arms b, and theirholes or depressions, when thus raised up, receive the points of thehooks d, and. hold them rigidly. By reversing the motion of the shaft D,the arms b are drawn away from the hooks, and they are released, andswung open to let go the block-hook; at the same time the lifting-rods Zdrop, and the springs t' throw down or ease down the heads as theyfollowthe rods Z. 4

Having thus fully described myrinvention, what I claim'therein als new,and desire to secure by Letters Patent, is-

In combination with hinged and dropping holding-heads, the lifting andlowering-rods Z, and the locking and unlocking arms l, all operated byone lever, or vone shaft, so that the whole may be within the control ofone person, substantially as and for the purpose described.
